|Here are some ideas that might let you recover the files, no guarantees.|
First, make a copy of the document
There’s a chance the corruption within the file may become worse over time
or you might destroy the file while trying to recover it.
Next, try saving the file in an different format.
Sometimes, using a format such as RTF or TXT
will cause some of Word’s codes to be stripped from the document,
which may fix the problem.
Try another word processor that supports Word documents like OpenOffice.
Or use a text editor like JEDIT to manually extract anything salvageable from the file.
You may also be able to recover the text portion of a document using Word’s text converter.
This filter will import straight ASCII text, you lose any Word formatting and nontext items such as graphics, but you should be able to extract the text information from the file.
